TOBACCO-DRIER.

SPECIFICATION forming part of Letters Patent No. 391,690, dated October 23, 1888.

Application filed September 13, 1886. Serial No. 213,370. (No model.)

To on whom it may concern.-

Be it known that I, DAVID B. OOOKE, acitizen of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in TObaccoDriers; and I do declare the following to be a full, clear, and ex-- U in tobacco-driers, and is intended to provide a device especially adapted to drying that brand of leaftobacco known to the trade as long-filler.

It consists in certain novel features hereinafter described and claimed.

In the annexed drawings, Figure 1 is a perspective view of the drying-screens, and Fig. 2 is a perspective view of the drying-room. Fig. 3 is avertical section through blower and heater, showing the passage-way for the air to and from drier.

Referring to the drawings by letters, A designates the drying-room,wl1ich is constructed with a false floor, B, above the floor proper, O, and having an open space, D, between one wall and the edge of the false floor. Outside or inside, as desired, of the room A, I arrange a blower, E, which communicates with a heater, F, and this heater is connected with the drying-room A by a tube or conductor, G, the end of which, a, enters the room and is bent downward, so as to throw the heated air to the floor in the operation of the device.

The letter J indicates a series of screens, to the sides of which are secured the perforated lugs I), through which pass the ropes Hat suitable points, so as to hold the screens apart at proper distances. The said screens are always held in horizontal position and parallel with each other and may be successively lowered, packing one upon the other as the to bacco is removed until all are emptied, when they may be repacked successively with fresh tobacco and drawn up one by one as packed and operated as before. It will be seen that as constructed the shelves are loaded and unloaded at a point within reach of the operator, which saves much time and labor. The top screen of the series or gang is provided with saddles K, which are adapted to receive the ropes H H, which pass through the lugs b of the screens J. The several screens are sus pended by ropes H H attached to the loops of the ropes H between the forked ends of the saddles K. By these means the series of screens may be raised or lowered at pleasure during the drying operation.

In operation the tobacco-leaves are spread upon the screens and the gang raised to near the ceiling of thedrying-room. The blower E is then set in motion and will draw air through the heater F and send itinto the drying-room through the tube G. The air will be heated in its passage through the heater F, and will consequently rise to the ceiling, passing through the screens in doing so and there by drying the tobacco. The air will become moist in its passage through the tobacco laden screens, and consequently heavier, and will fall to the door, passing through the space D and between the floors B and G, and thence passing into the heater E, where it is again heated and from which it is drawn by the blower E and forced back to thedrying-room. It will thus be seen that a constant circulation of the air is obtained and a steady stream of heated air is always rising through the screens and absorbing the moisture from the tobacco, which will be quickly and thoroughly dried. When the tobacco has been sufficiently dried, the screens are lowered, the dried tobacco re moved, and the former operation repeated.

Having described my invention, what [claim as new, and desire to secure by Letters Patent, 1s-

The combination of a series of adjustable screens with a drying-room having an exit through the floor at one side, an air-passage under the floor, a blower communicating with the open air exhausting the air from the drying-room through said passage and having a downwardly projecting delivering nozzle opening near the floor of the drying-room at the side opposite the exit, and a heater between the blower and the exhaust-passage, substantially as described.

In testimony whereof I affiX my signaturein presence of two witnesses.

DAVID B. OOOKE.
